    摘要： An olefin polymerization catalyst system includes a procatalyst component chosen from metal-ligand complexes of Formula (I): In Formula (I), each X is independently a monodentate or polydentate ligand that is neutral, monoanionic, or dianionic; the metal-ligand complex of Formula (I) is overall neutral; each Y1-Y4 and Y7-Y10 independently is selected from C or N such that six membered diaza (N2) or triaza (N3) rings are formed; wherein each R1 and R10 independently are chosen from (C1-C40) hydrocarbyl, substituted (C1-C40) hydrocarbyl, (C1-C40) heterohydrocarbyl, and substituted (C1-C40) heterohydrocarbyl or is absent; each R2, R3, R4, R7, R8, and R9 is chosen from hydrogen; (C1-C40) hydrocarbyl; substituted (C1-C40) hydrocarbyl; (C1-C40) heterohydrocarbyl; substituted (C1-C40) heterohydrocarbyl; halogen, nitro (NO2) or is absent; each R5 and R6 independently is chosen from (C1-C40) hydrocarbyl, substituted (C1-C40) hydrocarbyl, (C1-C40) heterohydrocarbyl, and substituted (C1-C40) heterohydrocarbyl.
